T0 @ZZ 'whom 'it may concern Be it known that I, HERBERT A. HENDRIX, citizen of the United States, residing at Albert Lea, in the countygof Freeborn and State of Minnesota, have invented certain new and useful Improvements in Combined Churns and Butter-Workers; and I do hereby declare theV following to be a full, clear, and exact description of the invention, such as will enable others skilled in theart to which it appertains to make and use the same. 'Y

My present invention relates to improvements in combined churns and butter workers, and is vin the nature of a division of my co-pending application, entitled Combined churn and butter worker led Sep# tember 10, 1913, under Serial Number 789,078, and maturedv into 17th, 1914, Number 1,117,569.

To the above end, .generally stated, the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a View, partly in plan and partly in horizontal central; section, takeny on the line w1 m1 vof Fig. 2; and Fig. 2 is a view, partly in elevation and partly in transverse vertical section, taken on the line m2 m2 of Fig. 1.

' All of the parts illustrated in the drawings are identified by the same characters which indicate like parts in the above identi-v fied co-pending application.

The numeral 1 indicates the drum shell and the numerals 2 and 3 indicate the drum heads. Axially located metallic plates 4 and 5 are secured, respectively, to the drum heads 2 and 3. Bolted, or otherwise rigidly secured, to the drum head 2 on top of the plate 4 is an oil and gear casing 6, having a bearing sleeve 7. A spider bracket 8 is bolted to the plate 5 and is provided with a short trunnion 9, spaced outward from the drum head 3, as shown in Fig. 1. The axes of the bearing sleeve 7 and trunnion 9 are co-incident with the axis of the drum. The drum is mounted for horizontal rotary motion on a pair of pedestals 10 and 11. The bearing sleeve 7 is loosely journaled on a fixed trunnion 12, bolted to the top of the pedestal 10, and the trunnion 9 is looselyI patent Novemberl journaled in a bearing box 13, bolted to the top of the pedestal 11.

A flanged recessed bearing hub 14 extends axially through the drum head 2 and plate 4 and its flange overlaps said plate and is secured by bolts 15 to the drum head 2. Extended axially through the plate 5 and the drum head 3 is a ianged tubular bearing hub `16, secured by bolts, or other means, to the plate 5. Loosely journaled on the hubs 14 and 16, is an axial working roller 17, having secured to one end a recessed head 18, which is telescoped onto the inner projecting end of the hub 14. In the other end of the working roller 17 is secured a short trunnion 19, loosely journaled in the inner end portion of the hub 16. A plug 2O has screw threaded engagement with the outer recessed portion of the hub 16 and a coiled spring 21 is compressed between the outer end of the trunnion 19 and the screw plug 20. Axially alined with the working roller 17 is a short shaft 22, one end of which has screw threaded engagement with a head 18, and the other end of which is loosely journaled in a seat formed in the hub` 14 and projects into the recessed portion of saidhub. The intermediate portion of the shaft 22 is expanded to form a ground valve 23, seated in the inner end of the hub 14. The spring 21 yieldingly holds this valve 23 seated in the end of the hub 14 to form an oil-tight joint between the casing 6 and the drum.

Coperating with the working rollers 17 is a pair of relatively small eccentrically located working rollers 24. In the ends of these rollers 24 are secured recessed bearings 25 and 26. The bearings 25 are loosely journaled on the flanged trunnions 27 secured to the head 2 and the bearings 26 are loosely journaled on the reduced inner ends of the hubs of stung boxes 28, secured to the drum head 3. It is important to note that the hubs of the stuiiing boxes 28 and the hub 16 close openings in the plate 5 and head 3 of diameters sufficient to permit the working rollers 24 to be passed therethrough. The hubs of the stuffing boxes 28 are vprovided with flanges bolted to the plate 5.

The working rollers 24 may be independently locked, at will, against rotation with respect to the drum by means of headed lock pins 29, mounted, for endwise sliding movement, in the stuliing boxes 28. These loclr pins 29 are formed with squared inner end portions that are slidably mounted in correspondingly formed seats in the hubs of lthe stuffing boxes 28, and are adapted to be moved into Vand out of sockets 31 formed in the bearings 26. The sockets 31 are also `squared in -cross section and, when the squared portions 30 of the lock pins 29 extend into the sockets 31, lock the rollers 24 to the hubs of the stufling boxes 28.

Rotary motion is imparted to the drum by driving means described and claimed in my Vabove identified (zo-pending application. For the purpose of this case, it is only necessary to note the following parts of the driving connections, to-wit: tubular Y driving shaft 32, spur gears 38, spur pinion 42, shipper lever 43, and plunger 47. The drum and spur gears v38 are driven from [the driving shaft 32 by connections, not shown. The spur pinion `42 is slidably vmounted on the squared end of the shaft 22, and is held for common rotation therewith. This spur pinion is adapted to be moved into and out of mesh with the spur gears 38 by the shipper lever 43, through the plunger `47. When thespur pinion 42 is out of mesh with the spur gears 38, the Asame is seated in :the recessed lportionof the hub -14 and the work-` ing roller 16 'is idle. `Oil, inwhich the .gears run, is introduced in 'to'the gear casing 6 through .a normally closed opening, not shown. This oil isprevented Vfrom entering the drum through the bearing 14, Vby the valve 23.5

-Secured the drum and coperating Vwith each workingvroller 24, is a lifting eignen. These lifting nights extend m- -diallyfrom the working rollers 24 and tangentially from the axial roller 17. As best i shown in Fig.v 2, these lifting flights termipin having an angular `extension adapted to be inserted into van. angular seat formed in theN eccentric working roller for locking the same against rotation with respect to the drum', at will.
